The House of the Scorpionby Nancy Farmer
Matteo Alacran was not Born; He was Harvested. His DNA came from El Patron, lord of a country called Opium -- a strip of poppy fields lying between the United States and what was once called Mexico. Matt's first cell split and divided inside a petri dish. Then he was placed in the womb of a cow, where he continued the miraculous journey from embryo to fetus to baby.
